【摘要】：随着国民经济建设的快速发展,导致国家对矿产资源的需求量也在不断的增加,尤其是煤炭资源。但是在急需煤炭资源的情况下,总是不停地传出矿难的消息,让人民群众对此感到忧心忡忡,国家安全部门对煤炭资源在矿井井下开采的稳定性和安全性看的愈来愈重要。矿井井下开采资源过程中的测绘工作,条件困难恶劣,又经常受到生产人员和施工方面的人员的影响,然而测量结果的准确性和可靠性直接与煤矿矿井经济效益和矿山安全生产相关,所以,矿山对井上下控制网导线测量工作的精度要求和作业模式的研究,以便于提高测量成果的质量和精度,从而让矿山工作人员安全生产并创造更大的效益。本论文主要是为了提高矿井井下测量成果的质量和精度,讨论和研究了井下控制网导线测量的方法。伴随着现代陀螺仪的快速发展和精度的提高,本论文针对《煤矿测量规程》中的一些规定的不足和严重滞后,在理论分析和实际观测数据处理两个方面进行了探讨,提出了可行的、符合现代矿井需求的作业模式和精度体系。针对矿井井下贯通误差预计做了陀螺定向导线最弱点分析、加测陀螺边合理长度和位置的分析,并且通过实际工作作业情况对矿井井下控制网加测陀螺定向边进行讨论得出最适合加测的方案,从而保证测量成果的精度质量。在井下控制网导线数据处理方法上,理应依据每个矿井井下控制网导线的使用情况来选择与之匹配的平差方法,没有要求一定要最高的精度质量。现在大多数煤矿经过多年的开采,井下控制网网形复杂,形成很多结点,所以针对所做的实验对象选择了结边网平差方法,相比较而言,简便而且严密。
[Abstract]:With the rapid development of the national economy, the demand for mineral resources is also increasing, especially for coal resources. But when coal resources are in urgent need, the news of mine disasters is always coming out. The people are worried about this. The state security department is increasingly important to the stability and safety of coal resources in underground mining. The mapping work in the process of underground mining resources in mines is difficult and difficult. Often affected by production personnel and construction personnel, however, the accuracy and reliability of the measurement results are directly related to the economic benefits of coal mines and mine safety, so, In order to improve the quality and accuracy of the survey results, mine research on the precision requirement and operation mode of the traverse survey of the up and down control network of the well is carried out in the mine. The purpose of this paper is to improve the quality and accuracy of underground survey results. With the rapid development of modern gyroscope and the improvement of precision, this paper aims at the deficiency and serious lag of some regulations in coal mine survey code. In this paper, two aspects of theoretical analysis and practical observation data processing are discussed, and a feasible operation mode and precision system according to the needs of modern mines are put forward. The reasonable length and position of the measuring gyroscope edge are analyzed, and the optimum scheme of adding the gyroscope orientation edge to the underground control network is obtained by discussing the actual working conditions. So as to ensure the accuracy and quality of the measurement results. In the data processing method of underground control network conductors, the adjustment method should be selected according to the usage of each underground control network wire. There is no requirement for the highest precision quality. Now, after many years of mining in most coal mines, the underground control network is complex and forms many nodes, so we choose the adjustment method of the closed edge net for the experimental object. Simple and tight.
